engine run on

A diode lets current flow in only one direction. I would use an amp meter to determine the aperage drew that the fans use. Then I would take that information to my local Radio Shack. Or If you dont have access to an DC ampmeter. You could say....It runs off a 20 amp fuse ..so size it for a bit more than 20.. I don't think having too big a doide will hurt you.

Some of the vendors sell them don't they?

I had the same problem till I installed the Mosely (sp?) Kit. The kit also helps other things. I'm know Mike Drew can tell you the benefits of the kit better them I. Good Luck

I had the same problem with a customers Pantera, the engine would turn off fine when cold and then not turn off when warmed up and fans on. I used the info at panteraplace.com and simply changed the fan to the accessory circuit and not the run circuit. It involved unplugging a connector from one fuse and hooking it to another. Very simple,problem solved.

Have a look in this PDF

I have this problem on my 79 only when I use the override switches. Am I right in saying they have the power connected to the wrong terminal and not accessory terminal in the fuse panel.

Fredrik's schematic is excellent.

The accessory circuit is connected to the ignition circuit through the ignition switch.
When you turn off the ignition you also disconnect the accessory circuit from the ignition circuit - this prevents anything on the accessory circuit from pumping any power back into the ignition circuit.

So Ron - yup changing those switches to take their power from the accessory circuit will work.
